Didn't work for me

I had high hopes for this serum but despite using it regularly for 3 months, I did not get the promised results.

Seems OK

Heard good reviews on this one, so was expecting a little more “oomph” from it. A run of the mill standard Vit C product IMO, and although fine, could argue that it is slightly over-priced.

A great vitamin C

I’ve found vitamin c can be very hot and miss. This one had good results however a very short life span for the size of bottle. The life span to bottle size drops my rating as I was left with waste

So cheap

Love this as it feels like high quality active, only used twice but already know it will be good

Love this!!

I must be on my 3rd bottle. I love this. Having tried other vit c serums and been disappointed, I gave this one a shot and haven’t looked back. It’s easy to apply and not greasy, absorbs easily and doesn’t pill like others do. It’s perfect with any moisturiser after and also makeup. The only downside is it has a weird smell that reminds me of beef crisps lol! But it goes away after a few seconds. In terms of results I’ve definitely noticed a difference since using it but give it time. It’s made my skin brighter (not lighter) and has helped even out tone and also helps with fading marks too but it’s not magic in a bottle either.

Seems good so far

I’ve not been using this for too long but so far so good, I’ve definitely noticed my skin feels glowier.  Fair warning though, it has a strong smell. Almost cat-like. But it does go away when you apply.

A good choice

I like the formula, sinks in nicely, good under makeup, but the amount is less than norma, for the price it should be 30mls.
